The short answer is “No”. You do not need to subscribe to Biddingo in order to access CNM bids.

Biddingo.com and BiddingoWest.com are subscription based services that aggregate Canadian bid opportunities.
However, Biddingo has a special agreement with CNM whereby CNM vendors can access and respond to CNM bids at no cost.

Currently, CNM vendors may see information that states that they are in a trial account or need to subscribe.
CNM vendors can ignore this type of information. Biddingo is working on suppressing such promotional material.

CNM Vendors with an interest in doing business with Canadian government agencies are certainly
welcome to subscribe or pay one time access fees to access Canadian bid details and documents.
